Temporal Distortion

What you see is real, but you can't see it this way with the naked eye. It is the result of thousands of 20-30 second exposures, edited together to produce the timelapse. This allows you to see the Milky Way, Aurora and other Phenonmena, in a way you wouldn't normally see them.

In the opening "Dakotalapse" title shot, you see bands of red and green moving across the sky. After asking several Astronomers, they are possible noctilucent clouds, airglow or faint Aurora. I never got a definite answer to what it is. You can also see the red and green bands in other shots.

At :53 and 2:17 seconds into the video you see a Meteor with a Persistent Train. Which is ionizing gases, which lasted over a half hour in the cameras frame. Phil Plait wrote an article about the phenomena here blogs.discovermagazine.com/badastronomy/2011/10/02/a-meteors-lingering-tale/
There is a second Meteor with a much shorter persistent train at 2:51 in the video. This one wasn't backlit by the moon like the first, and moves out of the frame quickly.

The Aurora were shot in central South Dakota in September 2011 and near Madison, Wisconsin on October 25, 2011.

Watch for two Deer at 1:27

Most of the video was shot near the White River in central South Dakota during September and October 2011, there are other shots from Arches National Park in Utah, and Canyon of the Ancients area of Colorado during June 2011.
